* Added new team flag B_TEAM_DEBUG_PREVENT_EXIT that prevents teams from exiting

via exit() (the calling thread will drop into the debugger instead).
* The DebugServer now uses this flag by default.
* Added TODO comment: the default debugger should already be able to set a flag
  like this in order to close a race condition between dropping a thread into
  the debugger and setting the flag.
* Cleaned up the debug_server sources a bit.
